0–100, higher is better. How it is calculated

智房网 is a Chinese real estate information platform launched recently in 2024, offering services including new home sales, second-hand housing transactions, rentals, real estate agency information, and industry news. The website targets Chinese property buyers, sellers, and renters, providing a comprehensive portal for real estate market information and listings. The platform positions itself as a nationwide real estate information hub with a medium-sized operational scale. Technically, the website uses the Destoon CMS platform, with JavaScript libraries such as jQuery 1.5.2 and 2.1.1, and standard HTML5 and CSS for presentation. Mobile optimization is basic, with a mobile redirect meta tag but no advanced responsive design detected. Performance is moderate, and SEO practices are adequately implemented with meta keywords and descriptions. From a security perspective, the site uses HTTPS and has domain transfer protection enabled, but lacks DNSSEC and important security headers like Content-Security-Policy and HSTS. The jQuery versions used are outdated, potentially exposing the site to vulnerabilities. No incident response or security policy information is provided, and no cookie consent mechanism is present, indicating limited privacy compliance. Overall, the website is functional and provides valuable real estate content but should improve its security posture and privacy compliance to enhance trust and protect users. The domain registration is consistent and transparent, supporting the legitimacy of the business.

This scan rated NIS2 with an earlier keyword method that is no longer shown; rescan for the per-article view. Risk management, continuity, supply chain, training, MFA, management oversight (Art. 20) and incident reporting (Art. 23) need internal evidence, and Guard cannot tell whether NIS2 applies to this organisation.

GDPR is indicative only, based on publicly visible signals: Articles 7, 12, 13 and 32 of Regulation (EU) 2016/679 and Article 5(3) of the ePrivacy Directive. Not a certification or legal assessment.

Priority findings

9 findings rated critical or high. Fix these first.

  1. Email security

    SPF, DKIM and DMARC stop others sending email that looks like it comes from your domain, a common route to phishing and invoice fraud.

    • Critical

      No email authentication configured

      Domain is vulnerable to email spoofing

      What to do: Implement SPF, DKIM, and DMARC immediately

  2. SSL/TLS

    TLS encrypts the connection and proves the site is really yours. Weak or expiring certificates trigger browser warnings and put traffic at risk.

    • Critical

      Unable to retrieve SSL certificate

      Could not establish secure connection to retrieve certificate information

      What to do: Check if the server is accessible and SSL/TLS is properly configured

  3. Network security

    Services reachable from the internet are the first thing attackers probe. Anything open that does not need to be should be closed.

    • Critical

      Critical Service Exposed: MySQL

      Port 3306 (MySQL) is publicly accessible - MySQL - Database server

      What to do: Immediately restrict access to MySQL using firewall or VPN

      • NIS2 21(2)(e)
      • IR 2024/2690 6.7.2(f): Implementing Regulation (EU) 2024/2690, Annex point 6.7.2(f): Network security
      • NIST CM-7: NIST SP 800-53 Rev. 5 CM-7: Least Functionality
      • NIST SC-7: NIST SP 800-53 Rev. 5 SC-7: Boundary Protection

  4. Security headers

    Security headers are instructions your web server sends to every visitor’s browser. Missing ones leave visitors more exposed to attacks such as clickjacking and injected scripts.

    • High

      Missing X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

    • High

      Missing Content-Security-Policy header

      Controls resources the browser is allowed to load

      What to do: Implement a Content-Security-Policy appropriate for your application

      • ASVS V3.4.3
      • OWASP Secure Headers: OWASP Secure Headers Project recommends Content-Security-Policy: default-src 'self'; form-action 'self'; base-uri 'self'; object-src 'none';…

Each check with its score, findings and the evidence it collected.

How this score is calculated

The security score runs 0–100, higher is better. It is the plain average of the security checks that completed in this scan, each counted equally. A check that could not run is left out: it counts neither as a pass nor as a fail.

Not counted

  • NIS2 outside view: Re-weights evidence from the TLS, email, DNS, network and hygiene checks, so counting it would count that evidence twice. Shown on its own.
  • OffSeq Observations: An AI reading of the site, useful context but not reproducible evidence. Shown on its own.

Findings that cap the score at 49

Each of these is serious on its own, so while any is present the site cannot rate better than high risk, however good the other checks are.

  • The certificate is not trusted by browsers
  • The website is not served over HTTPS
  • A database, remote desktop, file-sharing or Telnet service is reachable from the internet · found on this site
  • The page loads a script from a compromised source
  • The domain registration has expired
  • SPF authorises every server to send mail as the domain

Partial scans

When the site blocks Guard or most checks cannot run, the score covers only the checks that ran (usually DNS and email), is capped at 75 and is shown as partial, without a risk level.

Technical appendix

Business context, site observations and technical notes gathered during the scan, and the standards behind each reference.

Business context

Business profile

智房网 operates in the Chinese real estate sector as an information service platform, aggregating listings for new homes, second-hand properties, rentals, and commercial real estate. Its business model relies on providing comprehensive property data and related news to attract users and potentially monetize through advertising or premium listings. The platform targets a broad audience of property buyers, sellers, renters, and real estate professionals across China. The presence of multiple partner links suggests an ecosystem of related service providers. The recent domain registration aligns with a new market entrant or startup phase. The site’s content quality and breadth position it as a competitive player in the online real estate information market, though lacking advanced features or certifications.

Security posture

The website demonstrates a basic security posture with HTTPS enabled and domain transfer protection set. However, the absence of DNSSEC, security headers (CSP, HSTS, X-Frame-Options), and use of outdated JavaScript libraries represent vulnerabilities that could be exploited. No visible incident response or security contact information is provided, limiting transparency and readiness for security events. Privacy compliance is minimal, with no cookie consent or GDPR indicators. The site should prioritize implementing modern security headers, updating libraries, enabling DNSSEC, and publishing security policies to improve its security maturity and user trust.

Recommendations

  1. Enable DNSSEC on the domain to enhance DNS security and prevent spoofing.
  2. Implement essential security headers such as Content-Security-Policy, HSTS, X-Frame-Options, and X-Content-Type-Options.
  3. Update JavaScript libraries, especially jQuery, to the latest stable versions to mitigate known vulnerabilities.
  4. Add a cookie policy and consent mechanism to comply with privacy regulations and improve user trust.
  5. Publish clear security policies and incident response contact information to demonstrate security readiness and transparency.

Technical notes

Notes

The website is built on the Destoon CMS platform, a common choice for Chinese B2B and real estate sites. It uses legacy jQuery versions (1.5.2 and 2.1.1) alongside custom JavaScript and CSS. The HTML structure is valid with meta tags for SEO but lacks modern structured data formats like JSON-LD or Open Graph. Mobile optimization is basic, relying on a mobile redirect rather than responsive design. Performance is moderate with no explicit indicators of optimization or CDN usage. The hosting provider is not explicitly identified beyond the registrar July Name Limited. The site could benefit from modernization of its tech stack, improved mobile responsiveness, and enhanced accessibility features.
Standards and sources

Reference chips under each finding point to the standard, regulation or specification the finding relates to. They are taken from the official datasets below and mapped conservatively: a finding with no defensible link shows none. NIS2 and GDPR references mark where a finding is relevant evidence, not a compliance verdict. Implementing Regulation (EU) 2024/2690 binds digital infrastructure and digital service providers; for other entities it is the most detailed public reading of the Article 21 measures. WCAG, EN 301 549, European Accessibility Act and Web Accessibility Directive references name the requirement an automated accessibility rule relates to; they are not a conformance verdict.
